IMPRovEMENT AIn BELT-SHIPERS..

The Bchodnle xoferredvto in than Letten Patent and making part of the saine'.

To Aall whom t'may concern -lLBe it known-'that I, JOHN L; Oris, of Leeds, in lthe county of Hampshireand State of Massachusetts, 'have invented vcertain new and. useful Improvements in Belt-Shippers; and Ido herebyideclare: thefollowngtc'befa. 1h11, clear', and exact description -ot thel sam e; reference being hadto-'tbe accompanying draw-L ing making a. partof this specificatiolnirf which is representedv a perspective' viwof the shipper-as at- In the use of toggle orknuckle-joint levers, in ,con-- neotiomwith a slideyand spring'for 'moving andholdin g a driving-belt. v v e It further consists in the combination of the'togglef levers, slide, and spring, with a double or adjustble `11m1,drod, for operating the shipper, `as will beexplained. l

.To enable those-skilled yin the ait to makeand 'use my invention, I will proceed to describe. the same, with reference to the drawing,fi1st premisingthat the "shipper may be connected with' Aany ordinary shafthanger, or maybeattached to' aseparate hanger, as `mznrlzlepreferred.v I .v A representsa hanger, to which the bar or flame B may be connectedbyseirscrews passing through a,

slot, a, therein, by A ijvhiehit may be-adjusted.v

In guides bfoi'- atx'ysnitable'I kind on the bar or-fmme- B, a shipper' bar, O, is arranged, so as tobe moved thereon and therein. 1 f

Thisjshipper-barO may have upon any of its sides vthe usual loop or pins, for controlling a belt that passes through or between. them.

'.lo the shipperbar C there isattached one end of' a. coiledspring, o, the other, end thereof being con# nected to the :guide b, 'or any part of the bar, frame, or

other stationary point, so that the spring, in its normal L conditioinwill-hold .the shipper-bar in the position I shown in the-drawing.

. D-E are toggle or knuckle-joint levers, united at d by a rulejo'int.

`ed to the'shipper-bar G.

.At the joint d, or near thereto, is fastened a rod, e, which extends downward through a guiding slot, f, in the bar Vor frame B,- and its lower portion passes lanother rod, hi, passes and laps by, so that ,thev two o, may ship the belt.

, When the toggle-levers are `drawn down into a hori- 1 z'ontal position, which moves the shipper-bar and belt,

the spring'c is expanded, and the part-s will remain inv that position'and hold the Ybelt firmly to its pulley.'` When therbelt is to be shifted onto the other or loose pulley,- a slight* upward movement of the/rod will raise thietnggles firom their horizontal position,'and"the coli-2 1 traction of .the spring o completes the morementa.; 'Having thus fully described myinventiou,

by Letters Patent, is- Y 'r 1. In eombina'tionwith tlieshanger, the frame: or

2. In combination, the support or frame, theshipper-bar, toggle-levers', and spring, the adjustable rods, for bringing the handle Awithin conveniutposition for the operator, substantially as described.

'.lhe lower end of the lever D is pivoted' toy -the bar or frame 15, andthe-lower end 0f the lever E is pivotthrough a oouplingpiece, g, through-,or into which 4rods may be lengthened o1` shortened, or swung into. convenient position by the operator, who, by the handle What I claim therein'as new, and'desire to secure support, tle shippenbanthe toggle-levels, and spring,

substantially as and for the pnl-mise described.
